NCT03669614

Brief Summary

This is a Phase 1/2a randomized, double-blind, two-part, dose-ascending, multicenter study of AR-501 (gallium citrate) solution, administered via inhalation, in healthy adult and P. aeruginosa infected cystic fibrosis (CF) subjects. Phase 1 of the study in HV subjects will consist of a single-ascending-dose (SAD) cohort, followed by the HV multiple-ascending-dose (MAD) cohort. Phase 2a of the study in CF subjects will consist of a MAD study design. The study will evaluate the safety and pharmacokinetic (PK) profile of single and repeat administrations of inhaled AR-501 solution in healthy adults, and the safety, PK and efficacy of repeat administrations of inhaled AR-501 solution in P. aeruginosa infected CF subjects.

PARALLEL
Model Details: This study is a dose-escalation, placebo-controlled study where subjects are randomized to receive study drug or placebo. SAD and MAD HV Phases: The HV SAD and MAD will each include up to 24 adult subjects in 3 groups (8 per dose group) in each the SAD and MAD phase . All subjects will be randomly assigned in a 3:1 ratio to receive a single administration of active drug (12 HVs) or placebo (4 HVs). The CF MAD will evaluate 4 different dose levels in a total of 54 adult CF subjects (10 per dose level). The first 3 subjects (sentinel subjects) in the low, medium and high dose level will be randomly assigned at a 2:1 ratio to receive either AR-501 or placebo, for a total of 9 CF subjects. An expanded cohort will randomize 30 adult subjects at a 2:3:3:2 ratio to three doses of inhaled AR-501 or placebo. Subsequently an 80mg Ga dose (top dose) cohort will randomize subjects at a 2:1 ratio to receive either AR 501 or placebo for a total of 15 subjects , including 6 sentinel subjects.
